## Abstract

Disclosed is a vehicle lighting system including: an unmanned flying object configured to fly around a vehicle; a light source device provided in the vehicle, and a reflecting member provided in the unmanned flying object and configured to reflect light from the light source device and project the light around the vehicle.

## Claims

### Claim 1

A vehicle lighting system comprising:
an unmanned flying object configured to fly around a vehicle running on a ground;
a light source provided in the vehicle running on the ground;
a first reflector provided in the vehicle running on the ground and configured to reflect light from the light source to the unmanned flying object; and
a second reflector provided in the unmanned flying object and configured to reflect light from the first reflector such that the light from the light source of the vehicle is projected into an area around the vehicle running on the ground,
wherein the area includes a blind spot from the vehicle.

### Claim 2 (depends on 1)

The vehicle lighting system of claim 1, wherein the vehicle includes a controller configured to control a flight state of the unmanned flying object.

### Claim 3 (depends on 2)

The vehicle lighting system of claim 2, wherein the light source is configured to project a laser beam.

### Claim 4 (depends on 3)

The vehicle lighting system of claim 3, wherein the light source is configured to project blue light or violet light, and the second reflector includes a wavelength conversion layer configured to convert the blue light or the violet light from the light source into white light.

### Claim 5 (depends on 2)

The vehicle lighting system of claim 2, wherein the light source is configured to project blue light or violet light, and the second reflector includes a wavelength conversion layer configured to convert the blue light or the violet light from the light source into white light.

### Claim 6 (depends on 1)

The vehicle lighting system of claim 1, wherein the light source is configured to project a laser beam.

### Claim 7 (depends on 6)

The vehicle lighting system of claim 6, wherein the light source is configured to project blue light or violet light, and the second reflector includes a wavelength conversion layer configured to convert the blue light or the violet light from the light source into white light.

### Claim 8 (depends on 1)

The vehicle lighting system of claim 1, wherein the light source is configured to project blue light or violet light, and the second reflector includes a wavelength conversion layer configured to convert the blue light or the violet light from the light source into white light.

### Claim 9 (depends on 1)

The vehicle lighting system of claim 1, wherein the second reflector is configured to reflect the light from the light source so as to draw a figure and/or a letter around the vehicle.

### Claim 10 (depends on 1)

The vehicle lighting system of claim 1, wherein the light source of the vehicle includes a camera configured to capture an image of the unmanned flying object, and
a position of the unmanned flying object is detected by the camera.

### Claim 11 (depends on 1)

The vehicle lighting system of claim 1, wherein the vehicle includes an infrared ray receiver configured to detect light reflected from the second reflector provided in the unmanned flying object.
